New "display" for $3800 ???

I bought my 2004 Prius used 11 months ago, and love it. Recently I began to have some problems. The radio would shut off. A few minutes later it might turn back on. Then the display sometimes would quit showing the blinking arrows. Lately pressing the radio power button to turn it back on would sometimes take me to the Climate control screen!?!?

1. It is impossible to diagnose or repair a malfunctioning machine based on "It sometimes does ....". Trust me, I repair machines for a living.

2. That being said, I think a very good possibility is a loose ground connection. You may have to pay a couple $$$ to have a mechanic (with a wiring diagram) check for bad ground points.

All the circuts in a car eventually go to the ground. IF the ground is missing/bad, then voltage from control "A" can leak into device "B", causing all kind of strange behaviours when you hit a control button or switch.
